CSJ Crown Drill Bit, 3D Drill Diameter Range 38.00-38.99, Front-Locking Body with Internal Cooling for High-Speed Deep-Hole Drilling, Indexable Insert Drill / Side-Locking Drill Tip

The CSJ Crown Drill Bit is a high-performance, indexable insert drilling system engineered for high-speed, deep-hole machining. Featuring a 3D drilling depth capability and a secure front-locking body paired with a side-locking drill tip, this tool ensures exceptional stability and precision. Equipped with internal cooling channels, it effectively dissipates heat and evacuates chips, drastically extending tool life and achieving a superior surface finish in demanding operations.

Technical Parameters

Applications & Uses

• High-Speed Deep-Hole Drilling: Optimized for high-efficiency metal removal and stable deep-hole machining up to 3 times the diameter.

• Excellent Chip Evacuation: The internal cooling system forces coolant directly to the cutting edge, making it ideal for blind holes and deep cavity drilling where chip packing is a risk.

• Heavy-Duty Machining: Perfect for industries requiring high precision and durability, such as automotive manufacturing, aerospace, heavy machinery, and mold/die production.

• Multi-Material Versatility: Designed to handle a wide range of materials, including carbon steel, alloy steel, stainless steel, and cast iron (depending on the insert grade selected).
